17 import shipments a month
Diethyl ether is a DEA List I chemical, meaning importers must hold a valid DEA registration and obtain import permits for each shipment. Failure to comply can result in seizure and civil or criminal penalties, independent of CBP admissibility.
Beyond DEA permitting, diethyl ether is classified as a flammable liquid under DOT hazmat regulations, requiring proper UN packaging, hazmat labeling, and an accurate dangerous-goods declaration on the bill of lading. Ports may require advance notification for large-volume shipments.
